Configuring Vim
By default, vim runs in vi compatible mode. Some people might like this,
but we have a high preference to run vim in vim mode (else we wouldn't
have included vim in this book, but the original vi). Create the
/root/.vimrc by running the following:
cat > /root/.vimrc << "EOF"
" Begin /root/.vimrc
set nocompatible
set bs=2
" End /root/.vimrc
EOF
